VESSEL FOR TRANSPORTING AND PRESERVING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 590,993, date (1 October 5, 1897.

Application filed December 14,1896. Serial No. 615,603. (No model.)

To all whom itmacancer-IL:

Be i t known that. 1, PAUL LOCHMANN, a subcct-of the King of Saxony, residinp at Lcipsic- Gohlisfiaxot| \',Germauy,haveinvented a new and useful Improvement in Vessels for Transportin; and Preserving Liquids, of which the following is a full and exact specification.

This invention relates to a vessel for transporting and preserving liquids; andthe object of the same is to surround the liquidcontaining chamber with the body of gas acting upon the liquid within the chamber in such a way that the pressure of the gas both c liquid containing chamber will be the same, while the liquid itself discharged by the pressure of the pre- My inventimi consists of certain features of construction and combinations of parts to bc hereinafterdescribed and then particularly claimed.

- part of the ringd.

The accompanying drawingrepresents a longitudinal vertical section of a vessel for transporting and preserving liquids accordin; to this invention.

Referring to the drawing, a indicates the exterior casing of the device, and b the bottom of the casing. Fitted upon the mouth of the casing a is a ring d, which is provided with a reduced portion d, that is inserted within the mouth of the casing, and which is further provided with a rabbct-groove d extending around the inner upper corueror The ring 01 serves both for fixing the lid or cover got the casing to the same through the medium of it connecting screw or screws 10 and, for supporting the liquid-containing chamber 0. the connections perfectly laupacking e is seated in the raboccgroovo d or the ring (1, the lid or coveng resting and being firmly pressed upon said packing e,

air-tight, an annuwhilc the inner periphery of the ring engages with the .upper part of the liquid-containing chamber c; and thereby supports said chame her and forms a perfectly gas and airtight connection with the same. ring d maybe made of an such as glass, porcelain, or earthenware.

Inasmuch as the canal or ductf is rather constricted, the pressure of the gasfrom the casing a in the chamber 0' will only be gradu' ally lowered .when discharging thc chamberc by opening the cock 2'. chamber 0 can thus be discharged therefrom at a low pressure through the siphon, and i this pressure is gradually reduced as the liquid is forced out, so that an excessive foam-' stop-cock has been closed and has remained: closed for some time the pressure inside and outside the liquid-chamber will gradually assume an equilibrium.

To facilitate the introduction of the pre- 8o servi rig-gas into the casi 1;: a, a screw-threaded opening is formed in the lid or cover g, which receives the exteriorly-screw-threaded end 3/ of a plug 3, which is provided with a flange land a bore 0r passage r.

A valve 111 isapplicd to the lower end of the plug, so as to and prevent the gas escaping through the same. A screw-- cap 0 is screwed onto the screw-threaded upper end of the plug terposed between'the cap and the upper end of the plug,;so that when the cap isfitightly screwed home no gas can possibly pass out.

m is a handle which is hingedat n to the casing a, and whichat; its upper end is pfbrforated, so as to receive a screw-threaded stud 15, extending upwardly fromthe screw-cap 0, said upper end of the handle being secured to the cap by means of a nut p, screwed onto thestud t. Y f

For the purpose of cooling or warming the liquid contained in the chamber 0 a deep pocket u is arranged in the lid and extends, into the chamber, for the purpose of receivs, and a packing 'v is in- 2 IOO ing a tubular receptacle which may receive cold or hot water. The receptacle 9 can be readily removed and replaced in the pocket to through the medium of a handle at its 5 upper end.

As the chamber 8 is suspended or arranged within the casing a, said chamber is subjected to no pressure or strain excepting that which is exerted by the weight of the liquid con- 10 tained therein, inasmuch as the preservinggas pressesequally on both the inside and the outside of the chamber. Inasmuch as the preserving-gas enters the chamber 0 through theduct f when the liquid is-being i5 discharged, the full pressure of the preserving-gas does not permanently act on the liq uid excepting at the commencementof the discharge, while a gradual equilibrium of the pressure of the gasin the chamber 0 and in the casing a is maintained. By inclosing or enveloping the liquid-containing chamber 0 in the casing a it is prevented from being damaged from the exterior, as it hangs completely isolated in the preserving-gas.

chamber 0 and the vessel a are er'fectuated through the medium of the packing, e, before referred to, which can be renewed from time to time, if desired, while by disconnecting the 3p supporting-ring b, packing e, lid g, and the connecting screw or screws 10 the chamber and easing n ay be separated for the purpose of cleaning t em.

. Having thus described my invention, what I claim is' 1. The combination with an exteriorcasing, a. supporting-ring applied to the casing, and a, lid or cover applied to said supporting-ring and closing the upper end of the casing, of

The 25 firm connection and hermetic joining of the a liquid-con taining chamber suspended within said casing from said supporting-ring and having communication with the interior of the casing; substantially as set forth.

:3. The combination with an exterior casing, a ring fixed to the upper end of the casing, a lid or cover, and a liquidcontaining chamber provided with afsiphon, of a packing-ring interposed between the lid or cover and the first-named ring and resting against the exterior of the inner chamber, and being arranged to contact with the exterior of the inas set forth.

4. In a vessel for transporting and preserving liquids, an inclosing casing, a iid or cover fixed to the casing, a plug fixed to the lid and provided with an inlet opening or passage, a cap secured to said perforated plug, a handle movably connected with the exterior'casing, and means for detachably connecting the upper end of the handle with the said cap, substantially as set forth.

In testimony whereof I have signed my two subscribing witnesses.

PAUL LOCHMANN.
